SPE Disks and Cartridges
Waters Corp Oasis Vac Cartridge, 3 cc, 400 mg Sorbent, 60 μm
The Oasis HLB Vac Cartridge is a multi-purpose, reversed-phase sorbent with a water-wettable copolymer stable from pH 0–14. It provides analyte specificity and increased sensitivity for Solid Phase Extraction (SPE), allowing analytes to be retained even when loaded directly in an aqueous sample solution, offering excellent recoveries and higher retention.
- Water-wettable copolymer stable from pH 0–14.
- Eliminates condition and equilibration steps, reducing overall sample preparation time.
- Reduces solvent consumption by up to 70% and sample preparation time by 40%.
- Offers high recoveries and retention for diverse compounds.
- Hydrophilic-lipophilic balance retains both polar and reversed-phase compounds.
- Higher retention capacity improves recovery and reproducibility of SPE methods.
Waters Corp Waters Oasis MAX Flangeless Vac Cartridge, 1 cc, 10 mg, 30 μm
The 1 cc flangeless Oasis MAX cartridges contain a novel, mixed-mode polymeric sorbent optimized for higher selectivity and sensitivity in extracting acidic compounds with anion-exchange groups.
- Water wettable, maintaining higher retention and excellent recoveries even if the sorbent runs dry, eliminating the need to take extraordinary steps to keep sorbent beds from drying out before sample loading.
- Flangeless configuration allows the cartridges to be closely packed for processing in specialized automated SPE systems.
Waters Corp Waters Oasis PRiME HLB Plus Light Cartridge, 100 mg Sorbent, 50 pk
Oasis PRiME HLB sets a new performance standard for solid phase extraction cleanup in routine analysis. This sorbent provides reversed-phase cleanup for acidic, basic, and neutral compounds from complex sample matrices. It simplifies solid phase extraction with easy-to-follow protocols and produces cleaner samples by removing over 95% of common matrix interferences, including salts, proteins, and phospholipids. Its extreme water-wettability eliminates conditioning and equilibration steps, saving time and reducing solvent costs.
- Provides reversed-phase cleanup of acidic, basic, and neutral compounds from complex sample matrices.
- Produces cleaner samples by removing greater than 95% of common matrix interferences.
- Simplifies solid phase extraction with easy-to-follow protocols.
Waters Corp Waters Oasis WCX Cartridge, Mixed-Mode Weak Cation eXchange, 6 cc, 500 mg, 60 μm
Oasis WCX is a Mixed-Mode Weak Cation eXchange sorbent for strong bases and quaternary amines. It is stable from pH 0–14, water-wettable, and based on the Oasis HLB Copolymer, offering reversed-phase and ion exchange modes of retention for enhanced cleanup selectivity and sensitivity.
- Provides both reversed-phase and ion exchange modes of retention.
- Enables greater cleanup selectivity and sensitivity for acidic and/or basic compounds.
- Built upon the unique water-wettable Oasis HLB Copolymer.
- Allows for concentration of samples, especially with μElution Plate format (up to 15x concentration without evaporation).
- Offers a variety of tools for method development to optimize protocols for maximum selectivity and sensitivity.
- Helps achieve high recovery and reproducible results for a wide range of compounds.
Waters Corporation Sep-Pak Accell Plus QMA Carbonate Plus Light Cartridge, 46 mg Sorbent, 40 μm, 50 pk
These cartridges feature a silica-based, hydrophilic, strong anion-exchanger with a large pore size (300Å) and a carbonate counter-ion. They are designed for the extraction of anionic analytes from various solutions, especially where chloride interference is a concern.
- Silica-based, hydrophilic, strong anion-exchanger with 300Å pore size and carbonate counter-ion.
- Extracts anionic analytes from aqueous/non-aqueous solutions; avoids chloride interference.
- Light-style format with reduced internal diameter; enables minimal volume elution.
- Improves recoveries and reduces solvent consumption for limited samples.
- Ideal for isolating anionic proteins, acidic pigments, phenolic compounds, and inorganic anions.
- Manufactured in ISO 13485/9002-registered facility, compliant with cGMP for Class 1 Medical Devices.
